Apple just installed the largest piece of curved glass ever at its new headquarters

CBS Apple's new headquarters will feature the largest piece of curved glass in the world, claims chief designer Jony Ive.

The new campus was unveiled during a "60 Minutes" interview on Sunday night by Apple CEO Tim Cook and Ive. The building, set to be completed next year, is being worked on by 3,500 people.

But one of the coolest innovations of the new headquarters is its curved glass. More than 3,000 sheets of it will wrap around the entire building. All the panes were shipped from Southern Germany, where the manufacturer, Sedak, is located.

Cook visited Sedak to see the panes back in February. The biggest pieces are about 47 feet by 10.5 feet, according to Sedak's website.
